Q: I placed an order 3 days ago, but i haven't got my tracking No., what happened?

A: Dear friend, we received your order, but sorry to tell you that the item you bought is out of stock temporarily, i had sent you an -e-mail to inform this. It will arrive at stock within 2 days, when it is in stock, it will be shipped out at once and then send you the tracking No. after shipment.
